Or rather, very tiny ones...
After the arrival of my vials of solder from Hong Kong, I couldn't wait to try them out.
This is the top of the saddletank of the Coffeepot about to be soldered into place.
- position parts for soldering on the RSU (which is why it is all silvery - that is tin foil used as the negative terminal)
- apply spot of flux using pipette bottle
- apply single 0.7mm ball of solder using tweezers
- place RSU probe, and press [on] switch
Zap... and a very neat join with no cleaning up required. I like this :-)
If anyone else is thinking of ordering these solder balls, I'll just confirm that for 4mm, the 0.7mm size seems just right. Anything smaller is just too damn fiddly to manipulate easily, although I can see that "pouring" them into place will work well in certain circumstances with the very smallest size.
